ATTACHMENT FOR PLANERS.

Specification of Letters Patent.

Iratentecl July 10, 1906.

Application filed November 28,1905. Serial No. 289,509.

To all whom, it may concern:

Be it known that I, J OSEPI-I H. BAUER, a citizen of the United States, and a resident of the city of New York, Long Island City, borough of Queens, in the county of Queens and State of New York, have invented a new and Improved Attachment for Planers, of which the following is a full, clear, and exact description.

My invention relates to an attachment for planers and similar machine-tools adapted for modifying the ordinary operations performed by such tools. The principal ways in which I modify the operations of these tools are to turn the work so as to provide for cutting a screw-thread on it and to move it on the support upon which it is mounted in such a manner that the stationary tool past which it moves will make a out having a curved or slanting inner surface.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a plan of a portion of the planer, showing the preferred form of my improvements. Fig. 2 is a sectional view of the same on the line 2 2 of Fig. 1. Fig. 3is a side elevation of a portion of a guide which I prefer to employ. Fig. 4 is a sectional view on the line 4 4 of Fig. 3. Fig. 5 is a sectional view showing a portion of another guide used on my improved machine, taken on the line 5 5 of Fig. 1; and Fig. 6 is a sectional view on the line 6 6 of Fig. 2.

Upon the table 10 of a planer, shaper, or the like I place a housing or frame 11, having a bearing 12 for a head-stock 13. This headstock may be of any usual form adapted for supporting a chuck or for operating work by means of a dog or the like. Also upon the table I mount another housing 14, which has a tail-stock 15 of the usual or any desired character. These parts, being mounted upon the table, reciprocate or otherwise move with it in the ordinary manner, and a stationary tool 16, which is supported in an adjustable manner, as is usually the case, will cut a plane surface upon any work which may be held between the head-stock and the tail-stock, so long as the work is held in a stationary position with respect to the table. If, however, the work is moved with respect to the table, the cut of the tool is modified, and I will now describe how I prefer to manipulate the work in such a manner as to provide for cutting screw-threads and spiral grooves upon the work, using the ordinary planer with the tool mounted in the usual way.

Connected with the head-stock 13 is a shaft 17, upon which is a gear 18, meshing with a gear 19 on a shaft 20, mounted below the shaft 17. The gear 19 meshes with a reciprocable rack 21, mounted in guides 22 on the housing 11 and movable transversely of the table. This rack is provided with a projection 23, extending beyond the table, this projection having a stud 24, carrying a roller 25, which is adapted to move in a slot 26, carried in a guide 27. This guide is secured by bolts 28 or the like to adjustable brackets 29, which are pivotally mounted, by means of bolts 30, upon the body of the planer. These brackets have grooves 31 for receiving the bolts 28, and the adjustability of the guide 27 will be obvious. Then the table moves along the bed, it will be readily understood that the roller moves in the slot 26 and is so guided as to move the guide either outwardly or in wardly, as the conditions of the case may require. The reciprocation of the rack rotates or oscillates the gears 19 and 1S, and conse quently the head-stock 13, and so turns the work that the cutting-tool will cut the desired shape of groove or thread in its surface.

In order to provide for shifting the work laterally with respect to the table, thus affording means for cutting a curved or slanting surface upon the work, I mount the tail-stock '15 upon a slide 32, this slide working in guides 33 upon the housing 14. Upon this slide is a rack 34, meshing with a gear 35, which is operated by a gear 36. The latter gear is on a shaft 37, with which is rigidly connected an arm 38. This arm is provided with a roller 39, which operates in a slot 40 in a guide 41. This guide is provided with bolts 42 to hold it on brackets 43, which are pivoted on bolts 44 and are provided with slots 45 for receiving the bolts 42. The adjustment of this guide is obvious. It will be understood that ordinarily both of these guides are not employed at the same time; but it will be equally obvious that they can be and that a tapered screw-thread can thus be produced.

The movement of the tail-stock is utilized when tapered. work is to be operated upon, the said tail-stock elevating the tapered end of the work during the movement of the cutting-tool in such manner as to maintain the uppermost face of the object in proper relation with respect to the said cutting-tool.

When the machine is to be used for working metal, an ordinary face-plate may be used on the head-stock with the usual dog, This construction can also be used for wood, stone, and other materials; but for stone I prefer to somewhat modify the face-plate or work-holding element, so that the motion of the tail-stock can be accommodated and the stone turned after each screw-thread or groove is completed to present it in proper position for the next out. In stone-turning the work 46 is provided with a series of cavities or depressions 47 for use in holding it in the proper position with respect to the headstock. In order to provide means for entering these cavities and holding the work, a face-plate 48 is made with a series of elongated slots or notches 49 and a centering-pin 50 for centering the work. On this plate is mounted a disk 51, having studs 52 for entering the slots 49 and a central perforation 53, through which the centering-pin 50 passes. The disk also has a circular dovetail groove 54, in which sit two or more dovetail blocks 55, that are secured to the disk by means of screws 56, passing through a front plate 57. This plate has a central passage 58 for the center 50 and two or more projections 59 for entering the depressions 47. The angular position of the work can therefore be easily adjusted by loosening the screws 56 and moving the blocks in the dovetailed groove, while the wabbling motion of the work is accommodated by the flexible connection of the face-plate with the front plate or the play of the studs 52 in the slots 49.

Having thus described my invention, I claim- 1. An attachment for a planer, comprising a work-holder adapted to be secured to the planer'table, means for rotating the workholder operated by the reciprocation of the planertable, a tail-stock, means for moving the tail-stock on a line at an angle to the line of reciprocation of the work-holder, and means whereby the reciprocation of the workholder will operate the tail-stock-moving means.

2. An attachment for a planer, comprising a work-holder adapted to be secured to the planer-table, means operated by the reciprocation of the planer-table for rotating the work-holder, a tail-stock, a guide, and means connected with the tail-stock and engaging the guide for moving the tail-stock on a line at an angle to the line of reciprocation of the work-holder.

a reciprocable work-holder, a tail-stock, I means for moving the tail-stock on a line at an angle to the line of reciprocation of the work-holder, and means whereby the reciprocation of the work-holder will operate the tail-stock-moving means.

4. In a planer, the combination of a body, work-supporting means reciprocably mount ed upon the body, guides adjustably mountthe work-supporting means and engaging the guides for imparting rotating and lateral movement to the work-supporting means during the reciprocation thereof.

5. In a planer, the combination of a body, a table reciprocable thereon, a rack reciprocable transversely of the table, a guide adjustably mounted on the body for reciprocating said rack during the motion of the table, a head-stock, means for transmitting the motion of the rack to the head-stock to turn the latter, a second rack reciprocable transversely to the table, a second guide adjustably mounted on the body, means connected 'with said guide for moving the rack during the reciprocation of the table, a tail-stock, and means connected with the second rack for moving the tail transversely to the table.

6. In a planer, the combination of a body, a table reciprocably mounted thereon, worksupporting means upon the table, guiding means adjustably mounted on the body, means connected with the work-supporting means and engaging the guiding means for imparting rotary and lateral movement to the work during the reciprocation of the table, said work-supporting means comprising a face-plate, and a disk movably connected with said face-plate and having means for engaging the work.

7. The combination of a face-plate having a centering-pin and a series of perforations, a disk having a passage for the pin and studs to enter said perforations, and a front plate on the disk having means for engaging the work.

8. The combination of a face-plate having a centering-pin and a series of perforations, a disk having a passage for the pin and studs to enter said perforations and a front plate on the disk having means for engaging the work, said front plate being adjustably mounted on the disk.
